Class FramebufferSystem

constructor

• new FramebufferSystem(renderer): FramebufferSystem

• Parameters

  • renderer: Renderer

    The renderer this System works for.

  Returns FramebufferSystem

current

hasMRT

Readonly managedFramebuffers

renderer

viewport

writeDepthTexture

size

• get size(): {
      height: number;
      width: number;
      x: number;
      y: number;
  }

• Get the size of the current width and height. Returns object with width and height values.

  Returns {
      height: number;
      width: number;
      x: number;
      y: number;
  }

  • height: number

  • width: number

  • x: number

  • y: number

bind

• bind(framebuffer?, frame?, mipLevel?): void

• Bind a framebuffer.

  Parameters

  • Optional framebuffer: Framebuffer
  • Optional frame: Rectangle

    frame, default is framebuffer size
  • Optional mipLevel: number

    optional mip level to set on the framebuffer - defaults to 0

  Returns void

blit

• blit(framebuffer?, sourcePixels?, destPixels?): void

• Only works with WebGL2

  blits framebuffer to another of the same or bigger size after that target framebuffer is bound

  Fails with WebGL warning if blits multisample framebuffer to different size

  Parameters

  • Optional framebuffer: Framebuffer

    by default it blits "into itself", from renderBuffer to texture.
  • Optional sourcePixels: Rectangle

    source rectangle in pixels
  • Optional destPixels: Rectangle

    dest rectangle in pixels, assumed to be the same as sourcePixels

  Returns void

clear

• clear(r, g, b, a, mask?): void

• Clear the color of the context

  Parameters

  • r: number

    Red value from 0 to 1
  • g: number

    Green value from 0 to 1
  • b: number

    Blue value from 0 to 1
  • a: number

    Alpha value from 0 to 1
  • Optional mask: BUFFER_BITS

    Bitwise OR of masks that indicate the buffers to be cleared, by default COLOR and DEPTH buffers.

  Returns void

destroy

• destroy(): void

• Generic destroy methods to be overridden by the subclass

  Returns void

disposeAll

• disposeAll(contextLost?): void

• Disposes all framebuffers, but not textures bound to them.

  Parameters

  • Optional contextLost: boolean

    If context was lost, we suppress all delete function calls

  Returns void

disposeFramebuffer

• disposeFramebuffer(framebuffer, contextLost?): void

• Disposes framebuffer.

  Parameters

  • framebuffer: Framebuffer

    framebuffer that has to be disposed of
  • Optional contextLost: boolean

    If context was lost, we suppress all delete function calls

  Returns void

reset

• reset(): void

• Resets framebuffer stored state, binds screen framebuffer. Should be called before renderTexture reset().

  Returns void

setViewport

• setViewport(x, y, width, height): void

• Set the WebGLRenderingContext's viewport.

  Parameters

  • x: number

    X position of viewport
  • y: number

    Y position of viewport
  • width: number

    Width of viewport
  • height: number

    Height of viewport

  Returns void
